目的:探讨卡前列素氨丁三醇注射液(欣母沛)在预防前置胎盘剖宫产产后出血中的防治效果。方法:选择合并前置胎盘孕妇60例,随机分为对照组(胎儿娩出后宫体肌层注射缩宫素)、试验组(胎儿娩出后常规宫体肌层注射缩宫素,同时宫体肌层注射欣母沛),比较两者术中、术后2 h及术后24 h的出血量以及血红蛋白下降的变化。结果:试验组术中、术后2 h、24 h出血量分别为(219.90±26.39),(309.10±28.18),(323.67±22.13)mL,对照组分别为(367.60±35.86),(433.63±55.52),(428.37±55.87)mL,试验组出血量均少于对照组,P<0.05,差异有统计学意义。试验组血红蛋白下降为(1.04±0.27)mL,对照组(1.46±0.39)mL,试验组血红蛋白下降少于对照组,P<0.05,差异有统计学意义。结论:前置胎盘剖宫产术中预防性使用欣母沛,可明显减少术中和术后出血量,降低产后出血的发生率。
Objective: To investigate the preventive effect of carboprost trometamol injection (Xin-Pei-Pei) in the prevention of bleeding after cesarean section in pre-placenta. Methods: Sixty pregnant women with placenta previa were selected and randomly divided into control group (injection of oxytocin after uterine myometrium was delivered). The experimental group (oxytocin injection with conventional uterine myometrium after fetus delivery) Injection Yan Xin Pei), compared the two during surgery, 2 h after surgery and 24 h after the amount of bleeding and hemoglobin decreased. Results: The intraoperative and postoperative 2 h and 24 h hemorrhages were (219.90 ± 26.39), (309.10 ± 28.18) and (323.67 ± 22.13) mL, respectively, while those in the control group were (367.60 ± 35.86) and (433.63 ± 55.52), (428.37 ± 55.87) mL, the bleeding volume in the experimental group was less than that in the control group, P <0.05, the difference was statistically significant. The hemoglobin decreased (1.04 ± 0.27) mL in the test group and 1.46 ± 0.39 mL in the control group (P <0.05), the difference was statistically significant. Conclusions: Preventive use of Xinmi Pei in cesarean section of placenta previa can significantly reduce intraoperative and postoperative bleeding and reduce the incidence of postpartum hemorrhage.
